i dont know if this is accurate, i found this blog https://www.1031corp.com/exchanging-thoughts-blog/bid/90692/reporting-your-1031-exchange-on-form-882...
so as per this blog, i swapped dates betweek line 4 and 6, error is clear. it is just it is not 100% accurate.
is this some sort of work around to handle "reverse" vs "straight" exchange!?
